this had ntr? mmm I don't remember that ...

or it could be that I am confused
Oh it had it all right. I remember getting super annoyed with this game because of it. From what I remember it was only really shown with the the blond character that was a tsudere older sister. Eventually after you go down her path and she declares her love for you iirc. Another random character that you never see but has the same "abilities as you" wins/breaks down whatever you need to do to win the girls and thus breeds her, and iirc it is before you can even breed her yourself, so extra fuck you to the player.
It literally comes out of nowhere and from what I recall was completely stupid and unnecessary and seemed to only be there to "liven" up the world because at that point there are only references to other guys having the same abilities as the MC. Thus you see no girl is off limits to people like yourself.
This instance of NTR is what put me off of this game for years. And is an example of NTR done horribly wrong, since iirc the girl isn't even affected by being bred by someone else.
